Abstract
There is provided a cationic organic peroxyacid having the general formula wherein: R1 is an optionally substituted, linear or branched, C8-C12 alkyl or alkenyl group; R2 and R3 are each a methyl group; R4 is an optionally substituted, linear or branched C3-C5 alkyl or alkenyl group; p is 0 or 1; z is an integer selected from 0-3; y is an integer selected from 0-5; w is 0 or 1; and X- is a counter anion. This peroxyacid was found to have good bleaching performance without showing incompatibility with anionic surfactants.
Claims
exact text as granted — not AI-modifiedWe claim:
1. Cationic organic peroxyacid having the general formula ##STR8## wherein: R 1 is an optionally substituted, linear or branched, C 8 alkyl or alkenyl group, R 2 and R 3 are each a methyl group; R 4 is an optionally substituted, linear or branched C 5 alkyl or alkenyl group; p is 0 or 1; z is an integer selected from 0-3; y is an integer selected from 0-5; w is 0 or 1; and X - is a counter anion.
2. Peroxyacid according to claim 1, wherein p, z, y, and w are all 0.
3. Peroxyacid according to claim 1, wherein R 1 is an unsubstituted linear C 8 alkyl group.
4. Peroxyacid according to claim 1, wherein R 4 is an unsubstituted, linear C 5 alkyl group.
5. Peroxyacid according to claim 1, wherein X - is selected from the group consisting of NO 3 - , HSO 4 - , SO 4 2- , CH 3 SO 4 - , and R 5 (O) p SO 3 , wherein R 5 is a C 2 -C 20 substituted or unsubstituted radical selected from the group consisting of alkyl, alkenyl, and aryl group, and p is 0 or 1.
6. Peroxyacid according to claim 5, wherein X - is selected from sodium dodecyl sulphate (SDS), sodium fatty acid alpha sulphonate (SFAS) and tosylate.
7. Bleaching detergent composition, comprising from 3 to 40% by weight of one or more surface-active compounds, from 5 to 80% by weight of one or more detergency builders and an effective amount of a cationic peroxyacid according to claim 1, as the bleach component.
8. Composition according to claim 5, wherein the cationic peroxyacid is present at a concentration of from 0.5 to 15% by weight.
9. Bleaching additive composition, comprising from 50 to 90% by weight of a cationic peroxyacid according to claim 1, as the bleach component.Cited by (0)
